(Oregonian (Portland, OR) Via Acquire Media NewsEdge) Feb. 22--Two popular public databases were brought online by the Oregon secretary of state for the first time Saturday since they were shut down Feb. 4 after a cyber attack.

Hackers gained access to ORESTAR, which tracks campaign finance activity, and the Central Business Registry. Officials warned database users on Friday to change their passwords.

On Twitter, the Secretary of State's Office said the ORESTAR database was in a testing phase and that access could be intermittent over the weekend.

State officials don't believe credit card data was accessed in the hack, which they think was conducted by a foreign entity.

The state hired two contractors in response to the attack: Virtual Security Research to review security measures and ID Experts to reach out to affected users and answer calls. In total the contracts could cost up to $58,000.
